Since early 2019, researchers have been recording and analysing marsquakes as part of the InSight mission. This relies on a seismometer whose data acquisition and control electronics were developed at ETH Zurich. Using this data, the researchers have now measured the red planet’s crust, mantle and core — data that will help determine the formation […]

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede. This water vapor forms when ice from the moon’s surface sublimates — that is, turns from solid to gas.Scientists used new and archival datasets from NASA’s Hubble Space Telescope to make the discovery, published in the journal […]

Imagine a dust particle in a storm cloud, and you can get an idea of a neutron’s insignificance compared to the magnitude of the molecule it inhabits.But just as a dust mote might affect a cloud’s track, a neutron can influence the energy of its molecule despite being less than one-millionth its size. And now […]

When people see a toothbrush, a car, a tree — any individual object — their brain automatically associates it with other things it naturally occurs with, allowing humans to build context for their surroundings and set expectations for the world.By using machine-learning and brain imaging, researchers measured the extent of the “co-occurrence” phenomenon and identified […]
